Question

Aluminium chloride exists as dimer, Al2Cl6 in solid state as well as in solution of non-polar solvents such as benzene. When dissolved in water, it gives (A) [Al(OH)6]3- + 3HCl (B) [Al(H2O)6]3+ + 3Cl- (C) Al3+ + 3 Cl- (D) Al2 O3 + 6HCl

Al2Cl6 + 12H2O leftharpoons 2[Al(H2O)6]3+ + 6Cl-

Q. Aluminium chloride exists as dimer, $A l_{2} C l_{6}$ in solid state as well as in solution of non-polar solvents such as benzene. When dissolved in water, it gives

$[A l (O H)_{6}]^{3 -} + 3 H Cl$

$[A l (H_{2} O)_{6}]^{3 +} + 3 C l^{-}$

$A l^{3 +} + 3 C l^{-}$

$A l_{2} O_{3} + 6 H Cl$

$A l_{2} C l_{6} + 12 H_{2} O ⇌ 2 [A l (H_{2} O)_{6}]^{3 +} + 6 C l^{-}$
